Description
Technical field:
The present invention relates to a kind of sander sanding parts, be mainly used in sanding surface, and irregular metal and nonmetal flat work pieces surface are carried out quantitative sanding, belong to the sander component assembly and make the field three-ply board, thin thick china.
Background technology:
Existing abrasive finishing pad is made up of felt, Graphite cloth, metal integral pressing plate.Its weak point: the one, can't solve a hourglass and a difficult problem of leaking sand, the workpiece quality of being processed can't guarantee; The 2nd, Graphite cloth is very easily damaged, and its service life is extremely short.
Summary of the invention:
Purpose of design of the present invention: avoid the weak point in the background technology, designing a kind of one is can solve effectively by a sand surface of the work hourglass and a difficult problem of leaking sand; The 2nd, under the prerequisite of not damaging the rubber pneumatic bag pad, can greatly increase the service life.
Design of the present invention: 1. surface of the work hourglass and the main cause of leaking sand: because the graphite face of existing abrasive finishing pad can not be with being adjusted automatically by the convex-concave degree of sand surface of the work, and reality is just rough and uneven in surface by of sand workpiece itself, and therefore the veneer overlay that covers thereon also is uneven with regard to convex-concave.Enterprise strengthens the sanding amount a little for asking surface of the work sanding quality, causes inevitably by the part of sand surface of the work projection by hourglass; Otherwise,, then cause by the recessed part of sand surface of the work and leaked sand if the sanding amount is little.In order to solve this difficult problem, the present invention is with nonadjustable graphite pads structure in the abrasive finishing pad, be designed to graphite pads adjust automatically with the convex-concave degree on work piece surface himself height I shape key technical scheme---the graphite pads of abrasive finishing pad can automatically be adjusted its height with the convex-concave degree on work piece surface as key automatically, it is fully contacted fully with any position on workpiece to be machined surface, not only greatly improve the sanding quality of workpiece to be machined, and thoroughly solved a hourglass that exists in the prior art and a difficult problem of leaking sand.2. Graphite cloth's damage reasons very easily in the abrasive finishing pad: because Graphite cloth directly is wrapped on the metal integral pressing plate, when the sanding surface of the work, not only pressure is concentrated, the temperature height, and can't eliminate pressure effectively and concentrate, reduce temperature rise.Therefore, cause Graphite cloth's working life extremely short inevitably.In order to solve this difficult problem, the present invention separates Graphite cloth with rubber blanket, change into contactless---that is to say: Graphite cloth directly contacts with felt, and felt then covers several I shape key bottoms, and the rubber pneumatic bag pad is positioned on several I shape keys and is positioned at abrasive finishing pad pipe bed.The employing of this technical scheme, not only the graphite pads of abrasive finishing pad can be to the same surperficial convex-concave degree upper and lower displacement with workpiece to be machined of key, the convex-concave degree that has adapted to the workpiece to be machined surface, reached best sanding effect, and under the prerequisite of not damaging the rubber pneumatic bag pad, the pressure dispersion that the sanding surface of the work is produced, felt thermal insulation, the heat radiation of I shape key are greatly improved the service life of the Graphite cloth of abrasive finishing pad.Its organization plan: the 1. abrasive finishing method of air cushion pressure adjustable piano keyboard type abrasive finishing pad, the Graphite cloth of abrasive finishing pad at rubber pneumatic bag pad, I shape key with by the effect of sand workpiece face under with by rough and uneven in surface the fluctuating of sand workpiece face.2. air cushion pressure adjustable piano keyboard type abrasive finishing pad, constitute by abrasive finishing pad pipe bed (1), rubber pneumatic bag pad (3), several I shape keys (4), felt (5) and Graphite cloth (6), the top of several I shape keys (4) is positioned at abrasive finishing pad pipe bed (1) and is in-line arranges, abrasive finishing pad pipe bed (1) is for open type pipe bed or for having the pipe bed of several pilot holes, abrasive finishing pad pipe bed is square tube type or circular pipe type.Rubber pneumatic bag pad (3) is positioned at abrasive finishing pad pipe bed (1) and is positioned on several I shape keys (4); between rubber pneumatic bag pad (3) and abrasive finishing pad pipe bed inwall neonychium (2) is arranged; rubber pneumatic bag pad (3) is provided with intake valve and pressure-regulating valve, and the pressure in the rubber pneumatic bag pad is controlled at 0.3～2.0kg/cm
2Felt (5) is wrapped in the bottom of several I shape keys (4), and Graphite cloth is positioned on the felt (5).The inboard of I shape key (4) bottom is 2～20mm apart from the distance (8) in the abrasive finishing pad pipe bed outside, and the width of key (7) is 5～80mm.
The present invention compares with background technology, the one, with nonadjustable Graphite cloth in the abrasive finishing pad, be designed to Graphite cloth and adjust the I shape key technical scheme of himself height with the convex-concave degree on work piece surface automatically, the sanding band is fully contacted fully with any position on workpiece to be machined surface, not only greatly improve the sanding quality of workpiece to be machined, and thoroughly solved a hourglass that exists in the prior art and a difficult problem of leaking sand; The 2nd, Graphite cloth is separated with the rubber pneumatic bag pad, change into contactless, not only the graphite face of abrasive finishing pad can be as the surperficial convex-concave degree upper and lower displacement of key with workpiece to be machined, the convex-concave degree that has adapted to the workpiece to be machined surface, reached best sanding effect, and under the prerequisite of not damaging the rubber pneumatic bag pad, the pressure dispersion that the sanding surface of the work is produced, felt thermal insulation, the heat radiation of I shape key are greatly improved the service life of the Graphite cloth of abrasive finishing pad; The 3rd, easy to operate, stable mechanical performance, long service life, cost are low, easy to maintenance.
